R. David Murray1a14d3d2010-04-12 16:35:19 +000018- Issue #7585: difflib context and unified diffs now place a tab between
19 filename and date, conforming to the 'standards' they were originally
20 designed to follow. This improves compatibility with patch tools.
21
R. David Murray27ef9372010-04-12 14:26:06 +000022- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
23 character sets will now consistently use a Content-Transfer-Encoding of
24 7bit rather than sometimes being marked as 8bit.
25
Martin v. Löwis7f7765c2010-04-12 05:18:16 +000026- Issue #8330: Fix expected output in test_gdb.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +000040- Issue #7301: Add environment variable $PYTHONWARNINGS.
41
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000042- Issue #8329: Don't return the same lists from select.select when no fds are
43 changed.
44
Mark Dickinson82791672010-04-06 16:47:55 +000045- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
46 on 64-bit machines. The shift count for either left or right shift is
47 permitted to be up to sys.maxsize.
48
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000049- Ensure that tokenization of identifiers is not affected by locale.

Tarek Ziadé00002952010-04-03 08:37:59 +000051- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
52
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000053- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
54
Eric Smithd44b2fc2010-04-02 12:30:56 +000055- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
56 is called with a non-empty format string. This is an effort to
57 future-proof user code. If a derived class does not currently
58 implement __format__ but later adds its own __format__, it would
59 most likely break user code that had supplied a format string. This
60 will be changed to a DeprecationWaring in Python 3.3 and it will be
61 an error in Python 3.4.
62
Antoine Pitroua57df2c2010-03-31 21:32:15 +000063- Issue #8268: Old-style classes (not just instances) now support weak
64 references.
65
Victor Stinner6cbf90f2010-03-25 00:21:53 +000066- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
67 optimizations are disabled when --with-pydebug is used.
68
Victor Stinnerc7790ed2010-03-22 12:36:28 +000069- Issue #1583863: An unicode subclass can now override the __unicode__ method

Georg Brandlba83f822010-03-14 09:50:54 +000077 (SIGINT). If an error occurs while importing the site module, the error is
78 printed and Python exits. Initialize the GIL before importing the site

89 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
90 and `ssl.OPENSSL_VERSION_NUMBER`.
91
Benjamin Peterson76a23c12010-04-04 23:23:22 +000092- Issue #8310: Allow dis to examine new style classes.
93
Mark Dickinson8a950712010-04-03 15:47:46 +000094- Issue #8257: The Decimal construct now accepts a float instance
95 directly, converting that float to a Decimal of equal value:
96
97 >>> Decimal(1.1)
98 Decimal('1.100000000000000088817841970012523233890533447265625')
99
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000100- collections.Counter() now supports a subtract() method.
101
Raymond Hettingera551f312010-04-04 18:34:45 +0000102- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000103 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000104
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000105- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000106 old-style comparison functions to new-style key-functions.
107
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000108- Issue #8294: The Fraction constructor now accepts Decimal and float
109 instances directly.
110
Mark Dickinsone096e822010-04-02 10:17:07 +0000111- Issue #7279: Comparisons involving a Decimal signaling NaN now
112 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000113 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
114 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000115
Mark Dickinson99d80962010-04-02 08:53:22 +0000116- Issue #2531: Comparison operations between floats and Decimal
117 instances now return a result based on the numeric values of the
118 operands; previously they returned an arbitrary result based on
119 the relative ordering of id(float) and id(Decimal).
120
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000121- Issue #8233: When run as a script, py_compile.py optionally takes a single
122 argument `-` which tells it to read files to compile from stdin. Each line
123 is read on demand and the named file is compiled immediately. (Original
124 patch by Piotr Ożarowski).
125
126- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
127 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000128
Florent Xicluna58b65662010-03-30 16:29:03 +0000129- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
130 form feed (0x0C) are now considered linebreaks, as specified in Unicode
131 Standard Annex #14. See issue #7643.
Florent Xicluna22b24382010-03-30 08:24:06 +0000132 http://www.unicode.org/reports/tr14/
133
Mark Dickinson9588d992010-03-27 11:14:37 +0000134- Comparisons using one of <, <=, >, >= between a complex instance and
135 a Fractions instance now raise TypeError instead of returning
136 True/False. This makes Fraction <=> complex comparisons consistent with
137 int <=> complex, float <=> complex, and complex <=> complex comparisons.
138
Michael Foorde6410c52010-03-29 20:04:23 +0000139- Addition of ``WeakSet`` to the ``weakref`` module.

144 running from the build directory (POSIX only).
145

147
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000148- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
149 didn't support chflags() (for example ZFS under FreeBSD). The error is
150 now silenced.
151
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000152- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
153 deprecated.

157
Vinay Sajip804899b2010-03-22 15:29:01 +0000158- logging: Added getChild utility method to Logger and added isEnabledFor
159 method to LoggerAdapter.
160
Vinay Sajip31e928e2010-03-22 13:02:28 +0000161- Issue #8201: logging: Handle situation of non-ASCII and Unicode
162 logger names existing at the same time, causing a Unicode error
163 when configuration code attempted to sort the existing loggers.
164
Vinay Sajip3017a7b2010-03-22 12:33:08 +0000165- Issue #8200: logging: Handle errors when multiprocessing is not

169 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
170 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000171
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000172- Issue #8179: Fix macpath.realpath() on a non-existing path.

177 writing into objects supporting the new buffer API, for example bytearrays
178 or memoryviews.
179
Matthias Klose8b411682010-03-16 10:48:52 +0000180- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

187
Georg Brandlba83f822010-03-14 09:50:54 +0000188- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000189 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000190 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000191
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000192- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000193 for ``TimedRotatingFileHandler`` by using the modification time of an
194 existing log file to compute the next rollover time. If the log file does
195 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000196
Georg Brandlba83f822010-03-14 09:50:54 +0000197- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

204
Georg Brandlba83f822010-03-14 09:50:54 +0000205- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
206 a base64 transfer-encoded payload *after* decoding it; it no longer does.
207 This is a behavior change, so email's minor version number is now bumped, to
208 version 4.0.2, for the 2.7 release.
R. David Murray4617e502010-03-08 02:04:06 +0000209

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000234- Issue #8300: When passing a non-integer argument to struct.pack with any
235 integer format code, struct.pack first attempts to convert the non-integer
236 using its __index__ method. If that method is non-existent or raises
237 TypeError it goes on to try the __int__ method, as described below.
238
Georg Brandlba83f822010-03-14 09:50:54 +0000239- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
240 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
241 argument's __int__ method to convert to an integer before packing. It also
242 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
243 was inconsistent: __int__ was used for some integer codes but not for others,
244 and the set of integer codes for which it was used differed between native
245 packing and standard packing.)

280 function declaration, which was kept for backwards compatibility reasons,
281 is now removed (the macro was introduced in 1997!).
282
Larry Hastings402b73f2010-03-25 00:54:54 +0000283- Issue #7992: A replacement PyCObject API, PyCapsule, has been backported

Georg Brandlba83f822010-03-14 09:50:54 +0000540 file position when calling `truncate()`. It would previously change the file
541 position to the given argument, which goes against the tradition of

548 implementation is significantly faster and can be wrapped in a

550 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +0000641- The ``__complex__()`` method is now looked up on the class of instances to
642 make it consistent with other special methods.

645 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
646
Mark Dickinson1b34d252010-01-01 17:27:30 +0000647- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000648 DeprecationWarning when passed a float argument where an integer was expected.
649 These functions and methods now raise TypeError instead. The majority of the
650 effects of this change are in the extension modules, but some core functions
651 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
652 and many unicode/str methods.

667 least on IEEE 754 platforms), and in particular does not depend on the
668 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000817- Issue #3382: 'F' formatting for float and complex now convert the result to
818 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
819 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000820
Georg Brandlba83f822010-03-14 09:50:54 +0000821- Remove switch from "%f" formatting to "%g" formatting for floats larger than
822 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000823
Georg Brandlba83f822010-03-14 09:50:54 +0000824- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
825 1e-100 used to raise OverflowError, but now gives the requested 120
826 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000827

833 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
836 decimal string that's guaranteed to round back to x under correct rounding
837 (with round-half-to-even rounding mode). Previously it gave a string based on
838 rounding x to 17 decimal digits. repr(x) for a complex number behaves
839 similarly. On platforms where the correctly-rounded strtod and dtoa code is
840 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000841
Georg Brandlba83f822010-03-14 09:50:54 +0000842- Issue #7117: On almost all platforms: float-to-string and string-to-float
843 conversions within Python are now correctly rounded. Places these conversions
844 occur include: str for floats and complex numbers; the float and complex
845 constructors; old-style and new-style numeric formatting; serialization and
846 deserialization of floats and complex numbers using marshal, pickle and json;
847 parsing of float and imaginary literals in Python code; Decimal-to-float
848 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000849
Georg Brandlba83f822010-03-14 09:50:54 +0000850 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
851 providing correctly-rounded strtod and dtoa C functions. This code is
852 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
853 the C compiler. There may be a small number of platforms on which correct
854 operation of this code cannot be guaranteed, so the code is not used: notably,
855 this applies to platforms where the C double format is not IEEE 754 binary64,
856 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
857 and Python's configure script is unable to determine how to change the FPU
858 precision. On these platforms conversions use the platform strtod and dtoa,
859 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000860
Georg Brandlba83f822010-03-14 09:50:54 +0000861- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
862 uses the correctly-rounded string <-> float conversions described above (when
863 available), and so produces correctly rounded results that will display nicely
864 under the float repr. There are two related small changes: (1) round now
865 accepts any class with an ``__index__()`` method for its second argument (but
866 no longer accepts floats for the second argument), and (2) an excessively
867 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
868 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000872- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00001015- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1016 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1017 but with at least one decimal point and with a default precision
1018 of 12. Previously, the behavior the same but with a default precision of 6.
1019 This more closely matches ``str()``, and reduces surprises when adding
1020 alignment flags to the empty presentation type. This also affects the new
1021 complex.__format__ in the same way.
1022
1023- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
1024 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00001245- On windows, ``os.chdir()`` given unicode was not working if

1247 this code path is really executed because I cannot move to such directory on
1248 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001250- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1251 element is temporarily replaced with an equivalent frozenset. But the
1252 eventual KeyError would always report the empty ``frozenset()`` as the missing
1253 key. Now it correctly refers to the initial element.

Georg Brandlba83f822010-03-14 09:50:54 +00002507 leak-chasing test runs give sensible results. The previous method of reaping
2508 threads could return successfully while some Thread objects were still
2509 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00002510
Georg Brandlba83f822010-03-14 09:50:54 +00002511- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

2527 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002528 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2529 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002630 AttributeError instead of RuntimeError, depending in which C API call
2631 exactly the recursion limit is exceeded. Consequently, both exception types
2632 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002649- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2650
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002651- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2652 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2653 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2654 ``printf`` function, whereas PyString_FromFormat has an independent
2655 implementation and uses "%zd" on all platforms for size_t values.
2656 This makes a difference on win64, where ``printf`` needs "%Id" to display
2657 64bit values.
2658
Benjamin Peterson97179b02008-09-09 20:55:01 +00002659- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2660 error.
2661
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002662- Issue #3777: long() applied to a float object now always return a long
2663 object; previously an int would be returned for small values. the __long__
2664 method is allowed to return either an int or a long, but the behaviour of
2665 float objects should not change to respect backward compatibility.
2666
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002667- Issue #3751: str.rpartition would perform a left-partition when called with
2668 a unicode argument.
2669
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002670- Issue #3683: Fix compilation when --without-threads is given.
2671
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002672- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002673 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002674 was correctly parsed but parsing of subsequent arguments failed.
2675
Vinay Sajip35e3b032008-09-01 14:33:59 +00002676- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002677 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2678 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2679 when given a tuple of classes as second argument, were looking up
2680 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2681 type object.
2682
Neal Norwitz18aa3882008-08-24 05:04:52 +00002683- Fix crashes on memory allocation failure found with failmalloc.
2684
2685- Fix memory leaks found with valgrind and update suppressions file.
2686
2687- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2688
2689- Fix problem using wrong name in decimal module reported by pychecker.
2690
Christian Heimes7d4c3172008-08-22 19:47:25 +00002691- Silenced another compiler warning about a used but not defined
2692 function 'stringlib_contains_obj'.

2695 ``__delslice__``.
2696
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002697- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2698 library targets in the Makefile.
2699
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002700- Issue #1204: The configure script now tests for additional libraries
2701 that may be required when linking against readline. This fixes issues
2702 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2724
Nick Coghland2e09382008-09-11 12:11:06 +00002725- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002726 return a list or None rather than a custom object.
2727
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002728- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2752 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2753 for catch_warnings() also led to an improvement in the raising of a
2754 DeprecationWarning related to warnings.warn_explicit().
2755
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002756- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002820What's New in Python 2.6 beta 3?
2821================================
2822
Barry Warsaw07a4a382008-08-21 01:15:08 +00002823*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002824
2825Core and Builtins
2826-----------------
2827
Guido van Rossumf8402962008-08-20 15:01:50 +00002828- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2829 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2830 extensions do not automatically benefit from the class attribute
2831 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2832 to their tp_flags field if they care. This is a backwards
2833 compatibility feature; in 3.0, all types will use the cache by
2834 default.
2835
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002836- Keyword arguments can now follow starred arguments. (``f(a, *args,
2837 keyword=23)`` is now valid syntax.)
2838
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002839- ctypes function pointers that are COM methods have a boolean True
2840 value again.
2841
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002842- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2843 by denying s# to parse objects that have a releasebuffer procedure,
2844 and introducing s*.
2845
Georg Brandl1e13ea92008-08-11 09:07:59 +00002846- Issue #3537: Fix an assertion failure when an empty but presized dict
2847 object was stored in the freelist.
2848
Mark Dickinsonb6467572008-08-04 21:30:09 +00002849- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2850 ValueError consistently across platforms.
2851
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002852- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2853 (64bit Unix, for example), unichr() would truncate its argument and return
2854 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2855
Neal Norwitze7d8be82008-07-31 17:17:14 +00002856- Apply security patches from Apple.
2857
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002858- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2859 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2860
Antoine Pitrou92f82162008-07-25 22:22:08 +00002861- Issue #1819: function calls with several named parameters are now on
2862 average 35% faster (as measured by pybench).
2863
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002864- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2865 the python debugger steps into a class statement: the free variables (local
2866 variables defined in an outer scope) would be deleted from the outer scope.
2867
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002868- Issue #2620: Overflow checking when allocating or reallocating memory
2869 was not always being done properly in some python types and extension
2870 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2871 all been updated to perform better checks and places in the code that
2872 would previously leak memory on the error path when such an allocation
2873 failed have been fixed.

2877
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002878- Issue #3612: Added some missing basic types in ctypes.wintypes.
2879
Benjamin Petersone977ad42008-08-20 01:42:01 +00002880- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2881 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2882
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002883- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2884 version reported by these tools does not necessarily follow the python
2885 version numbering scheme, so the module is less strict when parsing it.
2886
Nick Coghlanf70385a2008-08-18 12:42:46 +00002887- Issue #2235: Added Py3k warnings for types which will become unhashable
2888 under the stricter __hash__ inheritance rules in 3.0. Several types
2889 which did not meet the rules for hash invariants and were already
2890 unhashable in 3.0 have now been explicitly flagged as unhashable in
2891 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2892 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2893
Brett Cannon88f801d2008-08-18 00:46:22 +00002894- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2895 imported into the module but exposed as part of the module's API.
2896
Brett Cannon7b96f072008-08-18 00:41:11 +00002897- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002901- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2902
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002903- Issue #3575: Incremental decoder's decode function now takes bytearray
2904 by using 's*' instead of 't#'.
2905
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002906- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002907 fails unicode conversion on 2nd parameter. (windows only)
2908
Facundo Batista94f243a2008-08-17 03:38:39 +00002909- Issue 2464. urllib2 now supports a malformation in the URL received
2910 in a redirect.
2911
Brett Cannonabe423e2008-08-16 21:47:07 +00002912- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002913 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002914
Facundo Batistaeb90b782008-08-16 14:44:07 +00002915- Issue #2776: fixed small issue when handling an URL with double slash

Antoine Pitroude781a42008-08-09 12:43:23 +00002963 asking for a specific length. This problem only affected files opened

3007
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003008- Issue #643841: The language reference now provides more detailed

3020-----------------
3021
Georg Brandl3e483f62008-07-16 22:57:41 +00003022- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3023 its methods now allow for items objects that can be converted to
3024 an integer using operator.index().
3025
Mark Dickinson64b7e502008-07-16 09:40:03 +00003026- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3027 produced a ValueError instead of giving the correct float.
3028
Eric Smitha5fa5a22008-07-16 00:11:49 +00003029- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3030 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3031
Mark Dickinson7103aa42008-07-15 19:08:33 +00003032- Issue #3008: the float type has a new instance method 'float.hex'
3033 and a new class method 'float.fromhex' to convert floating-point
3034 numbers to and from hexadecimal strings, respectively.
3035
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003036- Issue #2235: __hash__ is once again inherited by default. To allow
3037 collections.Hashable to remain meaningful in the presence of the
3038 default hash implementation (object.__hash__), it is now possible
3039 to explicit block inheritance of hash by setting __hash__=None at
3040 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3041 level.
3042
Nick Coghlanb028f502008-07-13 14:52:36 +00003043- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3044 the parent module cannot be found while performing an absolute import.
3045 This means that an incorrectly defined __package__ attribute will
3046 now only prevent relative imports in that module rather than causing
3047 all imports from that module to fail.
3048
Nick Coghlan14ff9942008-07-08 14:21:42 +00003049- Issue #2517: Allow unicode messages in Exceptions again by correctly

3059 another thread's dictionary.
3060
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003061- Issue #3004: Minor change to slice.indices(): the start and stop
3062 arguments are now treated identically, making the behaviour easier
3063 to describe and understand. For example, slice(None, -10,
3064 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3065 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3066 10, -1).
3067
Georg Brandl278fc502008-07-19 12:46:12 +00003068- Issue #3219: Calling a function with repeated keyword arguments,
3069 f(a=2, a=23), would not cause a syntax error. This was a regression
3070 from 2.4 caused by the switch to the new compiler.

3081 error when they failed.
3082
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003083- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003108- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3109 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003110 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003111 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003127- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00003498- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003499 environment to control the '-arch' flags that are used to build
3500 an extension. This was added for compatibility with Apple's build
3501 of Python.
3502
3503- The bundled OSX-specific copy of libbffi is now in sync with the version
3504 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
3505
Georg Brandl25c34082008-08-18 23:09:49 +00003506- The threading module gained aliases for names that will be removed in the

3515
Brett Cannonb61d8012008-05-11 23:39:04 +00003516- ``Lib/lib-old`` is now added to sys.path.
3517
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003518- On MacOS X it is now possible to install the framework in 64-bit
3519 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003520 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003521
3522 This is controlled by the configure argument ``--with-universal-archs``:
3523
3524 - ``--with-universal-archs=all``: install 4-way universal
3525
3526 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3527
3528 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3529
3530 This option should be used in combination with ``--enable-universalsdk=``.
3531
3532 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003582- Issue #1631171: Re-implement the 'warnings' module in C (the
3583 original Python code has been kept as backup). This will allow for
3584 using the 'warning's machinery in such places as the parser where
3585 use of pure Python code is not possible. Both the ``showarning()``
3586 and ``formatwarning()`` gain an optional 'line' argument which is
3587 not called by default for backwards-compatibility reasons. Setting
3588 ``warnings.showwarning()`` to an implementation that lacks support
3589 for the ``line`` argument will raise a DeprecationWarning.

3613
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003614- The getpass module has been improved on Unix. It now uses /dev/tty
3615 by default and uses stderr instead of stdout. A GetPassWarning is
3616 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003632 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Issue #2550: The approach used by client/server code for obtaining
3653 ports to listen on in network-oriented tests has been refined in an
3654 effort to facilitate running multiple instances of the entire
3655 regression test suite in parallel without issue.
3656 test_support.bind_port() has been fixed such that it will always
3657 return a unique port -- which wasn't always the case with the
3658 previous implementation, especially if socket options had been set
3659 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3660 new implementation of bind_port() will actually raise an exception
3661 if it is passed an AF_INET/SOCK_STREAM socket with either the
3662 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3663 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3664 the socket it's been passed. This currently only applies to
3665 Windows. This option prevents any other sockets from binding to the
3666 host/port we've bound to, thus removing the possibility of the
3667 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3668 when a second SOCK_STREAM socket binds and accepts to a host/port
3669 that's already been bound by another socket. The optional preferred
3670 port parameter to bind_port() has been removed. Under no
3671 circumstances should tests be hard coding ports!
3672
3673 test_support.find_unused_port() has also been introduced, which will
3674 pass a temporary socket object to bind_port() in order to obtain an
3675 unused port. The temporary socket object is then closed and
3676 deleted, and the port is returned. This method should only be used
3677 for obtaining an unused port in order to pass to an external program
3678 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3679 a parameter to a server-oriented class that doesn't give you direct
3680 access to the underlying socket used.
3681
3682 Finally, test_support.HOST has been introduced, which should be used
3683 for the host argument of any relevant socket calls (i.e. bind and
3684 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003685
3686 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003688 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3689 test_asynchat and test_socket_ssl.
3690
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691 It is now possible for multiple instances of the regression test
3692 suite to run in parallel without issue.

3960
Fred Drakea8ee94b2008-03-01 02:45:07 +00003961- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003962 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003968- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003969 issue 215555 for a discussion.
3970
Eric Smitha73fbe72008-02-23 03:09:44 +00003971- Added the future_builtins module, which contains hex() and oct().
3972 These are the PEP 3127 version of these functions, designed to be
3973 compatible with the hex() and oct() builtins from Python 3.0. They
3974 differ slightly in their output formats from the existing, unchanged
3975 Python 2.6 builtins. The expected usage of the future_builtins
3976 module is:
3977 from future_builtins import hex, oct
3978
Eric Smith7ef40bf2008-02-20 23:34:22 +00003979- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3980 exponents for exponents with absolute value < 100. Follows C99
3981 standard. This is a change on Windows, which would use 3 digits.
3982 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3983 so that any alterations it does to the resulting string will be
3984 available in stringlib/formatter.h (for float.__format__).
3985
Eric Smith5a3c1352008-02-19 13:21:56 +00003986- Implemented PEP 3101, Advanced String Formatting. This adds a new
3987 builtin format(); a format() method for str and unicode; a
3988 __format__() method to object, str, unicode, int, long, float, and
3989 datetime; the class string.Formatter; and the C API
3990 PyObject_Format().
3991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Fixed several potential crashes, all caused by specially crafted
3993 __del__ methods exploiting objects in temporarily inconsistent
3994 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003995
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003996- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997 prevent a possible crash: an Abstract Base Class would try to access
3998 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003999

4001 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004002
Georg Brandl3ee81df2008-05-17 18:14:43 +00004003- Clear all free lists during a gc.collect() of the highest generation
4004 in order to allow pymalloc to free more arenas. Python may give back
4005 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004007- Issue #2045: Fix an infinite recursion triggered when printing a
4008 subclass of collections.defaultdict, if its default_factory is set
4009 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004010
Christian Heimesf75dbef2008-02-08 00:11:31 +00004011- Fixed a minor memory leak in dictobject.c. The content of the free
4012 list was not freed on interpreter shutdown.
4013
Georg Brandl21e99f42010-03-07 15:23:59 +00004014- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004015 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4018 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004019 to compact the internal free lists of pre-allocted ints and floats.
4020
Georg Brandl3ee81df2008-05-17 18:14:43 +00004021- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4022 calls. Python expected the return type int but the fork familie
4023 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004024
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4026 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004027
Georg Brandl3ee81df2008-05-17 18:14:43 +00004028- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4029 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4032 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004034- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4035 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004036
Georg Brandl3ee81df2008-05-17 18:14:43 +00004037- Patch #1473257: generator objects gain a gi_code attribute. This is
4038 the same object as the func_code attribute of the function that
4039 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004040
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041- Issue #1920: "while 0" statements were completely removed by the
4042 compiler, even in the presence of an "else" clause, which is
4043 supposed to be run when the condition is false. Now the compiler
4044 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004045
Guido van Rossumeead05f2008-01-24 18:21:02 +00004046- A few crashers fixed: weakref_in_del.py (issue #1377858);
4047 loosing_dict_ref.py (issue #1303614, test67.py);
4048 borrowed_ref_[34].py (not in tracker).
4049
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004050- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004051 suppressed while an extension is loaded by calling SetErrorMode in
4052 dynload_win.c. The error is still reported properly.
4053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004055 several extension methods and modules do not work without unicode
4056 support.
4057
Georg Brandl26543b12008-01-21 18:36:51 +00004058- Issue #1882: when compiling code from a string, encoding cookies in the
4059 second line of code were not always recognized correctly.
4060
Georg Brandl14404b62008-01-19 19:27:05 +00004061- Issue #1679: "0x" was taken as a valid integer literal.
4062
Georg Brandl6caad7d2008-01-26 14:19:22 +00004063- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004064 added.
4065
Christian Heimesc94e2b52008-01-14 04:13:37 +00004066- sys.float_info / PyFloat_GetInfo: The floating point information
4067 object was converted from a dict to a specialized structseq object.
4068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Patch #1816: Added sys.flags structseq. It exposes the status of
4070 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004071
Georg Brandl3ee81df2008-05-17 18:14:43 +00004072- Objects/structseq.c: Implemented new structseq representation. The
4073 patch makes structseqs (e.g. the return value of os.stat) more
4074 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004075
Georg Brandl3ee81df2008-05-17 18:14:43 +00004076- Patch #1700288: added a type attribute cache that caches method
4077 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004078
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004079- Bug #1776: __import__() no longer accepts filenames on any platform.
4080 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004081
Georg Brandlaed6c662008-01-07 17:25:53 +00004082- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4083
Georg Brandl3ee81df2008-05-17 18:14:43 +00004084- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4085 envvar and sys.dont_write_bytecode attribute. All these can be set
4086 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004087
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- Improve some exception messages when Windows fails to load an
4089 extension module. Now we get for example '%1 is not a valid Win32
4090 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004091
Georg Brandl3ee81df2008-05-17 18:14:43 +00004092- Bug #1481296: Fixed long(float('nan')) != 0L.

4095 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004096
Christian Heimes0a8143f2007-12-18 23:22:54 +00004097- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004098 and INF. float("nan"), float("inf") and float("-inf") now work on
4099 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004100
Georg Brandl3ee81df2008-05-17 18:14:43 +00004101- Compiler now generates simpler and faster code for dictionary
4102 literals. The oparg for BUILD_MAP now indicates an estimated
4103 dictionary size. There is a new opcode, STORE_MAP, for adding
4104 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004105
Georg Brandl3ee81df2008-05-17 18:14:43 +00004106- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004114- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004115 SystemError.
4116
Nick Coghlanef01d822007-12-03 12:55:17 +00004117- PEP 366: Allow explicit relative imports when executing modules
4118 inside packages with the -m switch via a new module level
4119 __package__ attribute.

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00004128 attribute of an empty cell object.
4129
Georg Brandl3ee81df2008-05-17 18:14:43 +00004130- Issue #1460: The utf-7 incremental decoder did not accept truncated
4131 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004132
Georg Brandl3ee81df2008-05-17 18:14:43 +00004133- Patch #1739468: Directories and zipfiles containing a __main__.py
4134 file can now be directly executed by passing their name to the
4135 interpreter. The directory/zipfile is automatically inserted as the
4136 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004137
Georg Brandl3ee81df2008-05-17 18:14:43 +00004138- Issue #1265: Fix a problem with sys.settrace, if the tracing
4139 function uses a generator expression when at the same time the
4140 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004141
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004142- sets and frozensets now have an isdisjoint() method.
4143
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004144- optimize the performance of builtin.sum().
4145
Neal Norwitz44f326e2007-10-05 05:29:17 +00004146- Fix warnings found by the new version of the Coverity checker.
4147
Georg Brandl21e99f42010-03-07 15:23:59 +00004148- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4150 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1686386: Tuple's tp_repr did not take into account the
4153 possibility of having a self-referential tuple, which is possible
4154 from C code. Nor did object's tp_str consider that a type's tp_str
4155 could do something that could lead to an inifinite recursion.
4156 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4157 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004158
Georg Brandl3ee81df2008-05-17 18:14:43 +00004159- Issue #1164: It was possible to trigger deadlock when using the
4160 'print' statement to write to a file since the GIL was not released
4161 as needed. Now PyObject_Print() does the right thing along with
4162 various tp_print implementations of the built-in types and those in
4163 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Issue #1147: Exceptions were directly allowing string exceptions in
4166 their throw() method even though string exceptions no longer
4167 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004168
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169- Issue #1096: Prevent a segfault from getting the repr of a very
4170 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004171
Brett Cannon1e534b52007-09-07 04:18:30 +00004172- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004173 PyObject_Call() never calling back out to Python code to trigger
4174 recursion depth updates/checks. Required the creation of a static
4175 RuntimeError instance in case normalizing an exception put the
4176 recursion check value past its limit. Fixes crashers
4177 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004178
Georg Brandl3ee81df2008-05-17 18:14:43 +00004179- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004192- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193 __*__ attributes. (Some already existed, e.g., __doc__ and
4194 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004195
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004196- Add -3 option to the interpreter to warn about features that are
4197 deprecated and will be changed/removed in Python 3.0.
4198
Georg Brandl2134e752007-05-21 20:34:16 +00004199- Patch #1686487: you can now pass any mapping after '**' in function
4200 calls.
4201
Collin Winter62903052007-05-18 23:11:24 +00004202- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004203 "except E as target:". This is to provide forwards compatibility
4204 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004205
Brett Cannon229cee22007-05-05 01:34:02 +00004206- Deprecate BaseException.message as per PEP 352.
4207
Georg Brandl3ee81df2008-05-17 18:14:43 +00004208- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004209 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004210
Vinay Sajip8549ce32007-05-06 17:53:37 +00004211- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004212 setting a plain string, ie don't expand to single letter identifiers.
4213
Raymond Hettinger13936692007-04-11 18:40:58 +00004214- Request #1191699: Slices can now be pickled.
4215
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004216- Request #1193128: str.translate() now allows a None argument for
4217 translations that only remove characters without re-mapping the
4218 remaining characters.
4219
Georg Brandl5cb76c12007-03-21 09:00:39 +00004220- Patch #1682205: a TypeError while unpacking an iterable is no longer
4221 masked by a generic one with the message "unpack non-sequence".
4222
Neal Norwitzaa754b72007-03-21 06:39:48 +00004223- Remove unused file Python/fmod.c.
4224
Guido van Rossum143b5642007-03-23 04:58:42 +00004225- Bug #1683368: The object.__init__() and object.__new__() methods are
4226 now stricter in rejecting excess arguments. The only time when
4227 either allows excess arguments is when it is not overridden and the
4228 other one is. For backwards compatibility, when both are
4229 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004230 warning later). Also, type.__init__() insists on the same signature
4231 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004232
Georg Brandl3ee81df2008-05-17 18:14:43 +00004233- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4234 object to complex using its __complex__() method before falling back
4235 to the __float__() method. Therefore, the functions in the cmath
4236 module now can operate on objects that define a __complex__()
4237 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004238
Georg Brandl3ee81df2008-05-17 18:14:43 +00004239- Patch #1623563: allow __class__ assignment for classes with
4240 __slots__. The old and the new class are still required to have the
4241 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004242

Georg Brandlaa2321b2007-03-07 00:40:28 +00004273- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00004343- Bug #1545497: when given an explicit base, int() did ignore NULs
4344 embedded in the string to convert.
4345
Georg Brandl846f73a2006-10-08 07:11:54 +00004346- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004826 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00004860- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861 are set for invalid interpolation sequences that would lead to

4918 TestCase and TestSuite subclasses (not instances) are no longer

5293 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5294 silently miscode subclasses of those types. Now, it raises a
5295 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005296

Georg Brandl3ee81df2008-05-17 18:14:43 +00005311 time so that opening a database previously created with the DB_DUP
5312 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5313 opens. Specifically: dictionary assignment to a DB object will
5314 replace all values for a given key when the database allows
5315 duplicate values. DB users should use DB.put(k, v) when they want
5316 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005317

5323 characters with ASCII value less than 32. Also, it correctly quotes
5324 dots only if they occur on a single line, as opposed to the previous
5325 behavior of quoting dots if they are the second character of any
5326 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005327
